AXMINSTER TUBE FRAME.

Application filed July 19,

To all whom it may 00mm;

Be it known that I, HOWARD MASON, a citizen of the United States, residing at Amsterdam, in the county of Montgomery and State of New York, have invented new and useful Improvements in Axminster Tube Frames, of which the following is a specification.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to' similar parts in the several figures therein.

This invention relates to tube-frames such as are used in weaving Axminster carpets or other pile-fabric.

A frame of this type comprises in general a rigid longitudinal carrier-bar adapted to carry the yarn-spool, and also to form a substantial support for the tubes which control and guide the delivery of the yarn to the fabric in the weaving operation.

Tube frames of this type are more or less frail in construction and are subject tomany mishaps and smashes in the operation of the looms.

The principal object of the present invention is to provide a more substantial mounting of the tubes upon the carrier-bar and to facilitate repairs in case of a smash or accident to more or less of the tubes carried by the bar.

Other objects will appear in connection with the following description.

Fig. 1 of the drawings is a view in per spective of one of the angle-plates employed in my improved tube-frame.

Fig. 2 is a cross-section of the same.

Fig. 3 is a view in perspective showing the same with a number of tubes mounted thereupon applied to the carrier-bar.

Fig. 4: is a cross-section of the same.

Fig. 5 is a similar cross-section showing the carrier-bar in the form of a channel-iron.

Fig. 6 is a similar cross-section showing the carrier-bar made solid, and preferably of wood.

Fig. 7 is a view in front elevation of the tube-frame complete with the yarn-spools mounted thereupon.

Referring to Figs. 1, 2, 3 and 7 wherein the invention is shown in preferred form, 1 is the the carrier-bar shown as a hollow rectangular member having the usual bearing brackets, 22, for the spools, 3, which carry the 1922. Serial No. 575,973.

plates,each having a member, 5, extending along the front surface of the bar, and a member, 6, extending along the bottom surface of the bar, adjacent to the angular edge, formed at the junction of the front and bottom surfaces of the bar.

The member, 5, of each of these angleplates has its upper edge retroverted as shown at 7, and made in the form of teeth, 8, which are spaced apart and with relation to the tubes, 4, in accordance with the character of work for which the tube-frame is to be employed.

The tubes, 4, are mounted upon the respective angle-plates by resting upon the surface of the member, 5, and with the intake ends of the respective tubes interiorly engaged by the teeth, 8.

The tubes, 4, are preferably secured in this position by a soldered connection, 9, along an intermediate portion of the tubes at the junction of the members, 5 and 6, of the respective channel-irons.

Each tube is thus supported and braced or clamped at its intake end by one of the teeth, 8, inserted therewithin; and this engagement in connection with the soldered connection, 9, described, combines the tubes with the angle-plate in a substantial rigid structure.

The member, 5, of each angle-plate is formed with a plurality of hooks, 10, en-

gageable respectively with hookopenings, 11, formed in the front wall of the carrierbar, 1; and the member, 6, of each angleplate is formed with a plurality of screwopenings, 12, adapted to aline with screwthreaded openings, 13, formed in the bottom wall of the carrier-bar, 1.

Each angle-plate is mounted upon the bar, 1, by inserting the hooks, 10, in the respective openings, 11, and then inserting screws, 14,'through the respective screw-holes, 12, in the member, 6, of the angle-plate into the respective screw-threaded holes, 13, in the bottom wall of the bar.

The angle-iron having the members, 5 and 6, may be made in a single piece to sup port all of the tubes of the frame, or it may be made up of as many separate sections,

each supporting a number of tubes, as may bGtIlQSlIBCl.

1 am thus able to provide a light and substantially rigid support for the tubes;

and by employing a plurality of angle-plates having the members, 5, 6, I avoidthe necessity of removing all of the tubes in case of a smash or accident to certain only of the tubes.

Thus, if the damagedtubes are all located on a single angle-plate, that plate only need be removed for. repair or replacement of the injured tubes. r

By having the teeth, 8, extend interiorly of the intake ends of the respective tubes, a smooth? inlet surface is formed by 'theteeth which facilitates the passageof the yarn through the tubes. i i V For certain purposesof the inventionrthe carrier-bar may be made of any desired ma terial and of any desired form. Tlhus, in F 5, I have shown the bar in the form of a channel-iron, 1, this form permitting the construction to be otaerwise the same as above described in connection with the bar, 1. i I

InFigiG, l have shown a solid wooden bar, 1 to the front side of which the angleplates may besecured by screws, 15. ()therwise the construction is substantially as above described. a For certain purposes ofthe. invention, the carrier-bar n'iay be provided in anyl-znown manner with teeth, 8, having the functions above described.- F 1 i hat I claim as newanddesire to secure by Letters Patentis i 1.
